操作：
keyspace有两种策略：
createKEYSPACErootdata2WITHreplication={'class':'SimpleStrategy','replication_factor':2};	#复制策略：SimpleStrategy,冗余2份数据:
CREATEKEYSPACErootdata2WITHREPLICATION={'class':'NetworkTopologyStrategy','dc1':3};#复制策略：NetworkTopologyStrategy,冗余3份数据（配置可用）

查看key：
describerootdata2;

使用rootdata2创建表：
userootdata2;
createtableblog(idtimeuuid,titletext,contenttext,tagslist<text>,categorytext,primarykey(id));
INSERTINTOblog(id,title,tags)VALUES(Now(),'cassandratabletest',['cassandra','table']);
INSERTINTOblog(id,'table'])USINGTTL222;

删除单个keyspace：
dropkeyspacerootdata;
